That was the web circa 2010, when people were still using spinbots and link wheels as an SEO technique. They were the same articles, but with occasional words swapped out so it wasn't duplicate content in the eyes of Google. The Panda update for Google was largely responsible for cutting down on that behavior.
What's fascinating about natural language models for me, is that I assume it is already being applied to "spin" articles, and I imagine that is part of why Google kinda sucks to use right now.
